Minion method for maintaining a charcoal fire

As I understand it, Jim Minion discovered this awesome method for keeping a charcoal smoker hot for hours on end during a moment of sudden inspiration. This method is sheer genius, and in the smoking world, Jim will forever be a legend.

In a nutshell, a single chimney of lit charcoal is poured on top of a large pile of unlit charcoal. Over time, the lit charcoal slowly lights the charcoal below it. This method, when set up correctly, can produce constant heat for as long as 16 hours. This allows for that much-needed sleep during the long cooking times required by large cuts of meat such as brisket and Pork shoulder.
